A 100 mg piece of copper is heated to temperature T. The copper is then inserted into a 150 gram copper calorimeter that contains 200 grams of water. The system is initially at 16 degrees Celsius. After the copper mass is added, the final temperature of the mixture is 38 degrees Celsius. By checking the mass, it is determined that 1.2 grams of water evaporated. What was the temperature T?
In a liquid limit test, the moisture contents correspond to 20, 25 and 35 blows are 36% and 20%, 15% respectively. What is the liquid limit of the soil
While the swing bridge is closing with a constant rotation of 0.5 rad/s, a man runs along the roadway such that when d = 10 ft he is running outward from the center at 5ft/s with an acceleration of 2 ft/s^2, both measured relative to the roadway.
An equal-tangent crest vertical curve is designed with a PVI at station 110+00 and a PVC at station 107+43.3. if the high point is station 110+75.5 what is the design speed of he curve?

Determine the percent error n in replacing the sine and the tangent of an angle by the value of the angle in radians for angle values 5 degrees, 10 degrees, and 20 degrees. Explain the qualitative difference between the sine and tangent results
At standard pressure, 14.7 psi absolute, it holds 0.5-slug of water; rho = 1.94 slug/ft^3. For K = 300,000 psi, when it is filled, how many slugs of water must be added to increase the pressure to 10,000 psi
a freeway exit ramp has a single lane and consists entirely of a horizontal curve with a central angle of 90 degrees and a length of 628 ft. if the distance cleared from the centerline for sight distance is 19.4ft, what design speed was used
At one point in a pipeline, the water's speed is 3.00 m/s and the gauge pressure is 4.00×10^4 Pa. Find the gauge pressure at a second point in the line 11.0 m lower than the first if the pipe diameter at the second point is twice that at the first..
